Description

Technical Field

[0001] The present application relates to the field of detection and measurement technology, and in particular to a multifunctional aluminum alloy roughness measurement tool. Background Art

[0002] A surface roughness meter is a benchtop instrument used to assess the surface quality of parts. It can measure the surface roughness of a wide range of parts, including flat surfaces, inclined surfaces, external cylindrical surfaces, internal bores, deep grooves, and bearing raceways, achieving versatile and precise surface roughness measurement. Surface roughness measurement can be broadly categorized into contact and non-contact methods. Contact measurement methods primarily include comparison, die impression, and stylus methods. Existing contact-assisted measurement equipment has limitations due to its limited measurement angle. While handheld roughness meters overcome these limitations, they require the instrument to be placed horizontally on the surface of a horizontally positioned product, which can easily lead to scratches and large measurement errors. Furthermore, when measuring the inner and outer diameters of curved parts, the instrument lacks a surface to rest on, making it impossible to measure the roughness of these surfaces, thus failing to meet customer requirements. Commonly used non-contact measurement methods include light sectioning, real-time holography, speckle pattern analysis, astigmatism, optical heterodyning, AFM, and optical sensors. Consequently, these methods are complex and costly. Summary of the Invention
